Danger of Using 20% Salicylic Acid Gel for Home Chemical Peeling

Regarding your request for a formula to make a 20% salicylic acid gel for home chemical peeling:

I must strongly advise against using Salicylic Acid at a concentration of 20% on the face for chemical peeling at home. This concentration is extremely high and far exceeds the legal limit for cosmetic use (which is typically around 2%).

Using such a high concentration can cause severe chemical burns, scarring, hyperpigmentation, and permanent damage to your skin. As other members in this thread have also highlighted, even lower concentrations have caused significant issues.

For your safety, I cannot provide a formula for a 20% salicylic acid gel for home use. Chemical peeling, especially with high concentrations of active ingredients, should only be performed by a qualified dermatologist or skincare professional in a controlled environment.

If you are interested in learning more about Salicylic Acid or its safe uses in skincare at appropriate concentrations, I can provide general information.
